Supporting breastfeeding of small, sick and preterm neonates

Breastfeeding Measurement-What Does It Mean to "Wean?"

The term "weaning" is used heterogeneously in scientific and gray literature, with no commonly agreed-upon definition. Weaning can describe the gradual transition in the infant diet, usually from milk feedings to complementary foods, but it is also commonly used to describe any gradual transition between milks, foods, or feeding modalities. In an epidemiological context, it may also refer to changing breastfeeding rates within a cohort. The meaning of weaning has changed over time and may vary by the scientific assumptions applied to this period of human development. For these reasons, we propose that investigators avoid using the term weaning, and substitute it with more precise terminology. We present a series of proposed standard terms with corresponding definitions to guide more precise and accurate reporting of the various potential meanings of the term in the scientific literature. The objective is to improve reporting and reproducibility of research in the field of breastfeeding and human lactation.

Structured lactation support for mothers of very low birthweight preterm infants and establishment of human donor milk banks in German NICUs (Neo-MILK): protocol for a hybrid type 1 effectiveness-implementation cluster-randomised controlled trial

BACKGROUND

Human milk, especially mother's own milk (MOM), is vital for newborns and crucial for very low birthweight (VLBW, <1500 g) preterm infants, who face increased vulnerability. As the production of MOM may be impeded due to preterm birth, it is important to provide lactation support and establish human donor milk (HDM) banks to provide HDM when MOM is fully or initially absent. This protocol describes the design of a study evaluating the effectiveness, implementation and economic aspects of an intervention, which aims to ensure access to MOM or HDM for VLBW infants from the first day of life in German neonatal intensive care units (NICUs).

METHODS AND ANALYSIS

The hybrid type 1 effectiveness-implementation cluster-randomised controlled trial, using a stepped-wedge design, will be conducted in 15 level I and level II NICUs across Germany over 26 months. VLBW infants and their mothers will receive either standard care or the Neo-MILK intervention according to the NICU's group status. The primary outcome is the proportion of VLBW infants exclusively fed with MOM at NICU discharge. Secondary outcomes at infant level include feeding patterns, complications, length of stay and frequency of feeding with HDM. Maternal-level secondary outcomes cover lactation/breastfeeding decision and behaviour. A process evaluation and an economic analysis will accompany the study. The data set comprises survey and interview data and routinely collected data from medical records. Statistical analysis will be performed using generalised linear mixed models.

ETHICS AND DISSEMINATION

Data collection, storage and analysis comply with current data protection regulations. This study has received ethical approval from the Ethics Committee of the Medical Faculty of the University of Cologne and the local ethics committees of the participating NICUs. Results will be disseminated through peer-reviewed publications and on the project website.

Human milk feeding for moderate and late preterm infants at age 2 months: Insights from a cluster randomized controlled trial 2-month follow-up

Objective

Human milk (HM) is the optimal nutrition for infants; preterm infants demonstrate shorter HM feeding duration. Care interventions may increase HM feeding among preterm infants after NICU discharge. We compared Alberta Family Integrated Care (FICare) versus Standard Care on HM feeding in preterm infants at age 2 months.

Methods

We conducted a follow-up of a cluster randomized controlled trial of 455 infants and their mothers with data linked to the infant's 2-month public health visit. We used partial proportional odds to model group differences and factors associated with feeding type: exclusive HM (EHM), Non-EHM, or no HM (NHM).

Results

Compared to Standard Care, mothers in Alberta FICare were less likely to provide EHM versus NHM. There was no group difference between EHM and Non-EHM. Mothers with higher education who were on maternity leave or employed were more likely to provide EHM. Infants who received EHM at discharge were more likely to continue at age 2 months. Higher maternal breastfeeding self-efficacy at discharge was associated with a greater likelihood of EHM.

Conclusion

Alberta FICare was not associated with EHM feeding at age 2 months.

Innovation

Different factors predicted the three HM feeding categories, suggesting the need to individualize feeding supports.Trial Registration.ClinicalTrials.gov Identifier NCT02879799, retrospectively registered August 26, 2016.

Impact of theory of planned behavior based intervention on breastfeeding patterns of the mothers with preterm infants: a randomized trial

BACKGROUND

The birth of a preterm infant is considered a crisis for the mother and the family. Given the significance of breastfeeding for these high-risk infants, failure to initiate and maintain exclusive breastfeeding in this group of infants is a prevalent and serious problem. The aim of this research was to investigate the impact of Theory of Planned Behavior based intervention on breastfeeding patterns of the mothers with preterm infants: a randomized trial.

MATERIALS AND METHODS

This study is a field trial conducted in Isfahan, Iran in 2021-2022. It included 72 mothers of late preterm infants, divided into the intervention (n = 36) and control (n = 36) groups. The intervention group received four training sessions focused on breastfeeding patterns based on the Theory of Planned Behavior. Before, immediately after, and two and four months after the intervention, the constructs of the Theory of Planned Behavior related to breastfeeding patterns were assessed using a researcher-made questionnaire, and the infant's breastfeeding pattern was recorded. Statistical analysis was performed using SPSS version 19, g repeated measures ANCOVA, Bonferroni post hoc test, and chi-square test.

RESULTS

The results indicated that immediately after the intervention, as well as two and four months later, the mean scores for attitude (P < 0.001), subjective norms (P < 0.001), perceived behavioral control (P < 0.001), and behavioral intention (P < 0.001) were significantly higher in the intervention group than in the control group. Additionally, the results showed that, the rate of breastfeeding immediately, two months, and four months after the intervention was significantly higher in the intervention group than before the intervention (P < 0.001). However, in the control group, the rate of breastfeeding immediately, two months, and four months after the intervention was significantly lower than before the intervention (P < 0.001).

CONCLUSION

Interventions based on the Theory of Planned Behavior can improve exclusive breastfeeding in late preterm infants by changing the attitudes, subjective norms, perceived behavioral control and the behavioral intentions of the mothers of preterm infants.

Breastfeeding assistance for preterm and low birth weight infants: best practices implementation project

OBJECTIVE

To describe the process of best practices implementation for breastfeeding assistance for preterm and low birth weight infants.

METHOD

Participatory research that used the evidence implementation methodology of the JBI, held at a university hospital in southeastern Brazil, with the participation of a multidisciplinary team and managers.

STAGES

Situational diagnosis, baseline audit and feedback, protocol development, training, implementation, and monitoring.

RESULTS

Seven audit criteria were defined. In the baseline audit, three criteria were met, with eleven barriers to be resolved being listed. The strategies carried out were protocol development and multidisciplinary and intersectoral training. After the training, compliance was achieved with the seven criteria audited in the first follow-up audit and five in the second, emphasizing the increase in compliance after the implementation of the outlined strategies.

CONCLUSION

The project achieved the objective of improving evidence-based practice, and allowed the implementation of the institution's first breastfeeding protocol. However, it shows the need to maintain training for adherence and enculturation of new practices.

A Comparison of Ultrasound Imaging Texture Analyses During the Early Postpartum With the Mode of Delivery

BACKGROUND

Breastfeeding is beneficial to infants. However, cesarean section is reported to be a risk factor for unsuccessful breastfeeding.

RESEARCH AIMS

(1) To extract discriminating data from texture analysis of breast ultrasound images in the immediate postpartum period; and (2) to compare the analysis results according to delivery mode.

METHODS

A cross-sectional, prospective non-experimental design with a questionnaire and observational components was used. Participants (N = 30) were women who delivered neonates at a center from September 2020 to December 2020. The participants underwent ultrasound examination of bilateral breasts 7-14 days after delivery. Ultrasound images were collected for texture analysis. A questionnaire about breastfeeding patterns was given to the participants on the day of the ultrasound examination.

RESULTS

No significant differences were found in texture analysis between the breasts of participants who had undergone Cesarean section and vaginal deliveries. The mean volume of total human milk produced in 1 day was significantly greater in the vaginal delivery group than in the cesarean section group (M = 350.87 ml, SD = 183.83 vs. M = 186.20 ml, SD = 184.02; p = .017). The pain score due to breast engorgement measured subjectively by participants was significantly lower in the vaginal delivery group than in the cesarean section group (M = 2.8, SD = 0.86 vs. M = 3.4, SD = 0.63; p = .047).

CONCLUSION

Texture analysis of breast ultrasound images did not demonstrate difference between the cesarean section and vaginal delivery groups in the immediate postpartum period; nevertheless, cesarean section was independently associated with less successful breastfeeding.

Perinatal Factors Associated With Breastfeeding Trends After Preterm Birth <29 Weeks Gestation: Can We Predict Early Discontinuation?

OBJECTIVE

To determine the rates and perinatal factors associated with initiation and early discontinuation of breastfeeding among very preterm neonates.

METHODS

This was a retrospective cohort study of very preterm infants (<29 weeks gestation) admitted to 2 regional Level III neonatal intensive care units (NICUs) from January 1, 2015, to December 31, 2019. A national neonatal database was used to evaluate initiation and continuation rates of breastfeeding and associated perinatal factors. Stored nutrition profiles and delivery record books were used to determine feeding volumes associated with continuation of breastfeeding to hospital discharge for a subgroup of infants at a single site. Descriptive and inferential statistics were used to present the results between groups, and logistic regression modeling was used to calculate crude and adjusted odds ratios (OR) and 95% CI.

RESULTS

Of 391 eligible neonates, 84% initiated breastfeeding but only 38% continued to discharge. Interestingly, frequency of breastfeeding initiation (P < 0.001) and continuation (P < 0.001) declined over the study period. After adjustment for confounders, younger maternal age, earlier gestational age, cigarette smoking, and multiparity were significantly associated with early discontinuation of breastfeeding prior to hospital discharge. Early discontinuation of breastfeeding was also related to lower volumes of breastmilk by day 7 of life (P = 0.004).

CONCLUSION

Very preterm neonates are at high risk for non-initiation and early discontinuation of breastfeeding. The early postnatal period represents a critical time to establish breastmilk volumes, and the identification of key perinatal risk factors allows for early and targeted breastfeeding support.

Initiation of lactation and the provision of human milk to preterm infants in German neonatal intensive care units from the mothers' perspective

Background

If infants with a very low birth weight (VLBW) are to be fed exclusively with human milk, it is essential to focus on lactation initiation. The aim of the study is to learn more about the current state of lactation initiation and human milk provision in neonatal intensive care units in Germany from the mothers' perspective.

Methods

Written surveys were conducted with mothers of VLBW infants to learn more about the timing of initiation of lactation, pumping frequency during the first three days postpartum and feeding of the preterm infant during hospitalisation.

Results

The data of 437 mothers (response rate: 44.7%) were included in the analyses. Of these, only 7.8% stated that they had initiated lactation immediately after delivery and 38.2% within 6 h. In terms of pumping frequency, 50.1% pumped 7–9 times a day within the first 3 days postpartum; 60.9% reported that their infant received formula feedings during the hospital stay.

Conclusion

Overall, deficits were still evident with regard to the initiation of lactation in mothers of VLBW infants in Germany, resulting in a large proportion of VLBW infants receiving formula in the hospital.

Positive breastfeeding experiences and facilitators in mothers of preterm and low birthweight infants: a meta-ethnographic review

Background

Most qualitative research on breastfeeding the preterm or low-birthweight (LBW) infant has focused on negative insights; there are no comprehensive insights into how, when and why mothers experience positive breastfeeding experiences. We aimed to address this knowledge gap by exploring what characterizes and facilitates a positive breastfeeding experience in mothers of preterm and/or LBW infants.

Methods

A systematic review using meta-ethnographic methods was conducted. Search strategies involved a comprehensive search strategy on six bibliographic databases, citation tracking and reference checking. The analysis involved a reciprocal level of translation and a line of argument synthesis.

Results

Searches identified 1774 hits and 17 articles from 14 studies were included, representing the views of 697 mothers. A positive breastfeeding experience was identified as being ‘attuned’. Three themes and eight sub-themes were developed to describe what characterizes attuned breastfeeding. ‘Trusting the body and what it can do’, concerned how attuned breastfeeding was facilitated through understanding the bodily responses and capacity and feeling comfortable with holding the infant and to breastfeed. ‘Being emotionally present – in the here and now’ described the importance of feeling relaxed and reassured. ‘Experiencing mutual positive responses’, illuminated how attunement was related to feelings of mutuality - when the mother recognises the infant’s cues, responds to these signals and receives a positive response from the infant. The key factors to facilitate attuned breastfeeding were opportunities for prolonged close physical contact with the infant, positive relationships with and support from staff and peers, and being facilitated to breastfeed when the infant showed feeding cues.

Conclusions

This study provides new insights into what characterizes a positive breastfeeding experience and how staff can facilitate and enable mothers to achieve attuned breastfeeding. Improvements in units’ design, such as for rooming-in and having prolonged skin-to-skin contact, and care provided by knowledgeable, supportive and encouraging staff and peers, are crucial. The mother’s physical and emotional states and the infant’s behavioural responses and physiological signals should guide the process towards positive breastfeeding practices.

Tube Feeding Practices and Transition to Breastfeeding Experiences of Mothers of Preterm Infants at a Kangaroo Mother Care Unit of a Tertiary Hospital in South Africa

To receive human milk, most preterm infants initially receive the mothers’ expressed milk through a nasogastric tube. However, breast milk feeding the preterm infant and making the transition to direct breast-feeding come with significant challenges. The study explored and described the experiences of mothers of preterm infants regarding initiation and expressing breast milk, tube feeding practices, and transition to breastfeeding during the infants’ stay in a kangaroo care unit (KMC) of an academic hospital in South Africa. Using a qualitative design, focus group interviews were conducted with 38 mothers of preterm infants after discharge from the neonatal intensive care unit (NICU). We analyzed transcripts following the 5 steps for qualitative thematic data analysis. Tube feeding and breastfeeding preterm infants was challenging and exhausting for the mothers. Many described their experiences of initiating expression and sustaining milk supply as negative. They had constant concerns about their ability to produce adequate milk volumes to feed their infants. They had immense dislike of expressing, which they described as physically exhausting, stressful, and painful. Those who had initiated breastfeeding were highly motivated to breastfeed their preterm infants. They described breastfeeding as a positive bonding experience that they derived pleasure from. The mothers’ dislike of expressing was overshadowed by their emotional obligation toward their preterm infants. Although the KMC unit promotes breastfeeding, mothers encountered problems and struggled to initiate expression and sustain milk production. Mothers of extreme and very preterm infants need support to continue with milk expression during the long NICU and KMC stay.
